Referring to the drawings, the numeral primary air '12 indicates a supporting member of rectangular form which is of open construction'and is provided with alined elongated slots or openings 13 to adjustably receive thQIdOWHWfiIdl) extending lugs 14 of the burner holding members15 and are clamped thereto by screws 14:. The burners 16 positioned above the holding members 15 are connected thereto by screws 17 and 17 Each burner comprises the supply member 18, the standard 19, the burner member 20,

the lower burner casing 21 and the burner upper casing or cover 22. The standard 19 is preferably formed of soapstone or other like material and is provided with a central vertically extending bore 23 of Venturi shape into which extends the gas nozzle 24 forming part of the supply member 18. The upper end portion of the Venturi shaped bore is closed by a plug 25 forming part of the standard 19, which is also formed of soapstone or like material. When molded of soapstone or like material. more etficient radiation is provided, and the burner openings are less liable to carbonize and fill up and the parts may more easily be made.

The nozzle 24 is spaced a slight distance from the wall forming the Venturi bore to permit the entrance of air thereto through the air openings-25' extending through the supply member 18. A perforated valve late 26' pivotally mounted on the undersi e of the supply member 18 controls the supply of air to the Venturi bore. Said air valve is formed with an outwardly projecting bifurcated arm 26 for receiving the depending pin 27 of the control bar 28 which also controls the supply of gas to the Venturi bore through the valve 29 which is positioned in the supply member 18.

The upper portion of the standard 19' is provided with radial ports 30 which extend from the Venturi bore to the mixing chamber 31 formed by the lower casing 21 and adjacent parts. A mixing screen 32 positioned in the upper portion of the Venturi bore and covering the openings 30 thoroughly mixes the vapor and air passing therethrough. Annular conduction plates 33 positioned in the upper portion of the chamber 31 are provided with elongated perforations 33 which are radially'cf'fset with relation to each other and through which the mixed vapor passes upwardly from the mixing chamber 31. The burner member 20 is formed with annularly positioned upwardly extending truncated projections having openings 34 extending vertically therethrough which communicate with the chamber 31 above the conduction plates 33. The upper casing or cover 22 is positioned above the burner 20 to form an air space 35 and the casing is formed with upwardly extending perforated tubular portions 22' which surround the truncated projections 34 and permit the passage of air therearound.

The standard 19 is provided witlra plurality of vertically extending air ports 36 which open outwardly attheir lower ends, and at their upper ends communicate with the air space ,35 to furnish hot air around each individual burner and increase the 0thciency thereof A vapor generator in the form of two convolutions of a pipe 37, is positioned above the burner casing 22 and its opposite ends are connected to vertical pipes 38 and 39 extending upwardly alongside of the burner. The pipe 38 is the fuel supply pipe and leads from a source of supply. while. the pipe 39 connects with the valve 29 leading to the burner 20 so that oil or other fluid flowing upwardly through the pipe 38 and through the generator 37 will be heated and vaporized and flow downwardly through the pipe 39 to the burner in the form of a gas and be mixed with the air before burning. A needle valve 38 controls the fluid supply. The control bar 28 is connected to both gas valve 29 and the air valve 26 so that as the supply of gas is increased the supply of air will also be increased. A link 40 pivotally connected to one end ortion of'the bar 28 and the holdingmem er 15 provides forsaid bar being easily reciprocated to adjust the valves.

The outer and inner ring of tubular perforated portions 22 of the cover casing are joined together by upwardly extending flanges 41 to form a receptacle like space for holding liquid fuel which may be burned preliminarily to heat the gen ator in starting the burner.

To start the gas generator and burner in operation, a small quantity of oil or alcohol, preferably alcohol, is put into the grooves of the lower supporting plate and ignited. The combustion incidental thereto warms up the whole burner. Another small quantity of alcohol is also put into the depressions in the cover andthe same ignited, which results in heating the generating coil to the proper temperature for converting the liquid fuel into gas, after which the fuelsupply valve is opened slightly, the fuel being sprayed into one end of the generating coil, is promptly gasified, and passing through the coil goes to the gas supply valve which is then opened, the gas going through the nozzle into the Venturi bore and mixing with the air from the regulating air valve on its way up through the mixing screen and radial ports to the mixing chamber, then through openings in the conduction plates and through the burner openings where it is ignited by the flames of the mantle.

From the foregoing description, it will be seen that the gas generator and burner is of very simple construction and may be easily installed in an ordinary stove, and is well adapted for the purpose described.
